To all whom it may concern:

(Figs. 4 to 23, inclusive, enlarged.)

This invention relates to the construction of 70, a machine to performthe work on cartridgeshells commonly called trimmiug In the larger classof cartridges the edge of the heads require to be trimmed to bring themto a uniform size and shape, and to give to them a 7 smooth finish. Theoperation of drawing the shells from a disk of sheet metal leaves theedge at the mouth rough and of variable length in different shells. Itis necessary that the shells shall be of a uniform length and that theedge at the month shall be smooth; hence the shell at the month endrequires to be trimmed to produce this result. 'These operations oftrimming have heretofore been performed in separate machines, and in thelarger class the shells are more generally fed to the machine by hand.

The object of my invention is the construction of a machine which,receiving the shells in mass, may successively trim both the head 0 andmouth, or the mouth alone, should the head not require to be trimmed,whereby the constant presence of an attendant is avoided; and theinvention consists in the combination of elements producing an organizedmachine, 5 as more fully hereinafter described, and particularly recitedin the claims.

A represents the bed of the machine, which is supported upon suitablelegs, B; C, the driving-shaft arranged transversely across the ma- 10ochine at one end and supported in bearings D, power being applied tosaid shaft by any of the usual devices for such purpose.

E is a post arranged on the bed of the machine, and upon which the feedto supply the shells is supported. This feed may be of any of the knownfeeds adapted to successively supply shells from a mass to the machine.(Not necessary to be shown or described in this specification, as itconstitutes no part of the invention.) I would here state, however,

that the feed particularly adapted for this class of machine is that forwhich Letters Patent of the United States, No. 317,396, were granted tothis applicant, dated May 5, 1885. On the driving-shaft is abevel-pinion, F, working into a corresponding pinion, G, on a verticalshaft, H, which shaft is designed to operate the feed, the post E andshaft H being shown as broken oifin the several figures. The shells, byany suitable feed, are delivered into a fixed tube, 1, head downward, asseen in Fig. 4.

Below the tube I, and upon the transverse shaft J, the carrier K ishung, adapted to re ceive the shells from the tube I and present themfor subsequent operation. The carrier K is preferably of quadrant shape,and on its face is constructed with a vertical recess, L, which, whenthe carrier is in the position seen in Fig. 4, stands directly beneaththe tube, and forms, substantially, a continuation of the tube. Therecess L has a shoulder, M, in its sides, against which the head of theshell falling therein from the tube may rest, as seen in Figs. 4 and 9,Fig. 10 showing the recess in transverse section.

To the shaft J and the carrier K an oscillatory or rocking movement isimparted from a cam, N, on the driving-shaft, through a lever, O, hungupon a fulcrum at P, one arm of the lever working upon the face of thecam, the other arm extending toward the carrier and connected to an arm,R, on the shaft J, by a link, S. (See Figs. 4 and 7.) The action of thecam is to depress the arm in connection with the carrier, so as to bringthe carrier to the position seen in Fig. 4, with its recess directlybeneath the tube I, and to support it in that position during a certainportion of the revolution. To turn thelever in the opposite directionwhen the cam permits, a spring, T, is provided, tending to liftupon theforward arm of the lever, and so that when the depression of the campermits the carrier K will be turned from the position seen in Fig. 4 tothat seen in Fig. 7that is, will receive substantially a one-fourthrevolntion-and so that under such movement the shell which has beenreceived into the carrier from the tube will be transferred into aposition in a horizontal line, as seen in Fig.7. To support the shellduring this transfer, a pair of jaws, U U, are arranged in the carrier,said jaws being adapted to embrace the cartridge-shell. They are hung inthe carrier on vertical pivots V V, (see Fig. 11,) the tails WV of thejaws extending rearward, and to the jaws springs X are applied, thetendency of which is to force the forward or grasping end of the jawsupon the shell when permitted so to do. When the carrier stands in itsup position or receiving position, as seen in Fig. 4, the tails of thejaws have entered between the convergent faces of a stationary cam, Y,(see Fig. 11,) so that the jaws in that position are separated to permitthe shell to pass down between them; but as the carrier commences itsrotative move ment the tails of the jaws U escape from the cam Y andspring toward each other, as indicated in broken lines, Fig. 11, and soas to grasp the shell and hold it to prevent its displacement during therotative movement of the carrier from the position seen in Fig. 4 tothat seen in Fig. 7. The back ofthe carrier is of segment shape, theaxis upon which the carrier rotates being the cent-er of such segment,and so that as the carrier turns from the position seen in Fig. 4 tothat seen in Fig. 7 the back of the carrier passes beneath the lower ordelivery end of the tube I, and so that the next shell above the onedelivered to the carrier may ride upon the back of the carrier, and besupported thereby until the carrier returns after having delivered itsfirst shell. grasp of the jaws U. Thus the carrier may form a stop orsupport for the column of shells during the transfer of the shell whichenters the carrier; but I prefer to provide a check independent of thecarrier. To this end I arrange a vertical shaft, (1, parallel with thetube, (see Fig.9,) and from this shaft an arm, I), extends toward thetube, and from the said arm 2) a stud, d, extends inward through anopening in the side of the tube, so that if the shaft a be turned toforce the arm b toward the tube the stud will engage the shell, which atthat time happens to be at that point in the tube, and as seen in Figs.4, 7, and 15. The bearing movement ofthe stud upon the shell-that is,the inward movement of the arm-is prod need by a spring, 0, (see Fig.3,) so that when the arm I) is free the spring forces it inward and sothat the stud will engage the shell in the tube, as seen in Figs. 4 and7; but when the arm is turned away, as indicated inbroken lines, Fig.7,then the column of shells will be free to fall. To thus relieve thecolumn of shells, a second arm, f, extends from the shaft a, (see Figs.9and 12,) the end of which stands in the path of a shoulder orprojection, g, on the carrier, and so that as the carrier is turned fromthe position of receiving the shell (see Fig. 4) to that of deliveringthe shell, as seen in Fig. 7, and during the last part of the movementof the carrier, the shoulder g strikes the end of the arinfand turns itwith the shaft a, as indicated in broken lines,Fig. 12, correspondinglyturning the arm I) to take the stud from engagement with the shell inthe tube, as seen in Fig. 7 in dotted lines. \Vhen the shell is thusrelieved, the column will force the lowest shell downward, as indicatedin broken lines,

Then the next shell will drop into the r Fig. 7, until the head restsupon the back of the carrier K; then as the carrier returns the shellthus resting will ride upon the back of the carrier, and so soon as thearm f is released from engagement with the carrier the spring e returnsthe shaft (4 and forces the stud d inward and against the second shell,as seen in Fig. 7, and so that the second shell will be engaged withsufficient force to sup port the column of shells above, and so thatwhen the carrier has reached its up position, as seen in Fig. 4, theshell which had been, riding upon the back of the carrier will fall intothe recess on the face of the carrier and l e grasped by the jaws, asbefore described. The rotative movement of the carrier transferring theshell from a vertical to the horizontal position, (seen in Fig. 7,)presents the shell in line with a chuck designed to receive the shell.The chuck, as here represented, consists of four jaws, h. (See Figs. 16and 19.) These jaws are arranged in ahead, i, the back of the jaws ofconical shape, and so that an advance or forward movement of the jawswill give to them an inward radial or grasping movement, or a retreat ofthe jaws will permit them to open; and that the jaws 1lltty thus beforced to open, springs Z are arranged between the adjacent jaws. (SeeFig. 19.) The head carrying thejaws is supported in a bearing, m,extending up from the bed. The head i is in connection with arectangular frame,n, which is made fast to a tubular arbor, 0, supportedin bearings r 0', (see Fig. 1,) to which power is applied through apulley, t, to cause the arbor, with the chuck-frame n, to revolverapidly. The axis of the arbor is at right angles to the axis of thedrivingshaft, and is in line with the axis of the shell presented by thecarrier to the chuck. The jaws h h are operated by a system of levers,as shown in Figs. 4 and 16, the system there being shown as duplicates,although asinglesystern may answerthe purpose. In the frame a, anddiametrically opposite each other, levers u are hung, each upon afulcrum, w. The inner arm of the levers extends into an annular groovein a collar, 2, arranged upon a cylindrical portion of chuck-jaws and soas to bear forward against the shoulder on the jaws. From the other armof the levers u a connec tion, 3, extends to the arm of like levers, 4,at the rear end ofthe chuck-frame, the levers4 being each hung upon afulcrum, 5. To these levers 4 a spring, 6, is applied, the tendency ofwhich is to so turn the levers 4 as to impart to the collar 2 a rearmovement, tending to release the jaws to permit the retreat and openingmovement. The reverse movement of the levers is imparted by a tubularsleeve, 7, within the arbor o. The forward or outer end of the sleeve 7bears against the inner end of the levers 4. At the rear end of thesleeve 7 is an annular groove, 8, into which a short arm, 9,0fthelevers,hun'g upon a fulcrum, 10, enters. The other arm, 11, of the saidlevers extends forward, and between them enters a cam-like ablelongitudinally thereon.

collar, 12, surrounding the arbor 0, and mov- Longitudinal movement isimparted to the collar 12 from a side grooved cam, 13, through a lever,14,and connecting-rod 15, which connects said lever 14 with a forkedlever, 16, working in an annular groove, 17, in the collar 12, and sothat at the proper time a rear movement is imparted to the collar 12,tending to force it be tween the longer arms, 11, of thesleeve-actuating levers, as seen in Fig. 16, or in the re versedirection to withdraw the collar12 from between the said arms, so as toallow them to approach each other. This mechanism for moving the sleeve7 is a common onein many machines where an automatic chuck-closingdevice is desirable. As the collar 12 enters between the arms 11 itturns the levers upon their fulcrum and gives tothe shorter arms, 9, aforward movement, which is imparted to the sleeve 7, and this forwardmovement of the sleeve 7 turns the levers 4 against the action of thesprings 6, and gives to the levers a a corresponding movement,which isimparted to the collar 2, and this movement of the collar rier is forcedbetween the jaws of the chuck,

as from the position in Fig. 7 to that in Fig. 16, or as from theposition in broken lines,Fig. 4, to the position in solid lines samefigure. The transfer of the shell from the carrier to the chuckisproduced by a longitudinally-re ciprocating follower, 18, attached toand moving with a slide, 19. The slide 19 is arranged betweenlongitudinal guides 20 on the side of the machine. (See Figs. 4 and 21.)Thelongitudinal movement is imparted to the slide 19 by a crank-wheel,21, on the driving-shaft through a connecting-rod, 22, between saidcrank-wheel and slide. Vhen the carrier has been turned to present theshell into the position seen in broken lines, Fig. 7, then the follower18 advances, as indicated in broken lines, Fig. 7, striking the head ofthe shell then in the carrier, forcing it forward into the chuck, asseen in Figs. 4 and 16, and, having thus transferred the shell from thecarrier to the chuck, the follower retreats. So soon as the shell hasbeen thus transferred to the chuck, the jaws of the chuck are forcedinward, as before described, and so as to grasp the shell and hold it ina concentric position in. and so that it may revolve with, the chuck.Thus held the flange or head of the shell projects outside the nose ofthe jaws, and the mouth extends inward beyond the tail of the jaws.After having thus delivered the shell to the chuck, the carrier returnsto the posi tion in Fig. 4, to receive a second shell, and

during such time the trimming of the shell is performed.

I will first describe the mechanism for trimming the head. Thecutter-holder 23 is hung upon the side of the frame on centers orbearings 24, (see Fig. 1,) and so that the axis of motion of thecutter-holder is parallel with the axis of the shell to be trimmed. Tothis holder a rocking movement is imparted from a side faced cam, 25, onthe driving-shaft, which actuates a rock-shaft, 26,which extendslongitudinally beneath the bed, (see Fig. 2,) an arm from the rock-shaftextending up and so as to work against the side of the cam 25, as seenin Figs. 2 and 3, and in broken lines, Fig. 22. From the rock-shaft anarm, 28,extends downward,and from the arm 28aconnectiou, 29, is madewith an arm, 30, extending down from the cutteuholder 23, (see Fig. 22,)and so that at a predetermined time the cam 25 imparts to thecutter-holder a swinging movement toward and from the shell, and asindicated in Fig. 22. At its upper end the cutter-holder is provided.with a cutter, 31. The cutting-edge of this cutter is shapedcorresponding to the required shape of the flange. As shown in thedrawings, this cutter is made in the shape of a disk, having an annulargroove in its edge corresponding to the cut to be made, and then at onepoint in its periphery a portion is cut away, as indicated in Fig. 22,so as to present a cut ting edge in the periphery of the cutter to thehead of the shell, as indicated in Fig. 22. As the cutter is thusbrought up against the head, it trims the edge of the head to the required shape and size. After having done this work, the cutter iswithdrawn by the return of the shaft 26, under the action of a spring,32, on the said shaft, (see Fig. 2,) the said spring being a helicalspring around the shaft, one end fixed to a support on the bed, and theother to a collar on the shaft, as shown. At the same time the head isbeing trimmed, the trimming operation at the opposite end is going on.The mouth-trimming apparatus is shown in Figs. 16, 17, and 18. Insidethe sleeve 7 is a tube, 33, which at the forward end extends into thechuck-frame 41.. At its opposite end it is made fast in a head, 34, 011the bed of the machine, so that it has neither longitudinal or rotativemovement, the arbor 0 and the sleeve 7 revolving freely upon the outsideof the fixed tube 33. On the end of the tube 33, and within thechuckframe, a cross-head, 35, is applied, and made fast to that end ofthe tube. (See Fig. 17.) To the cross-head a yoke, 36, is hung uponpivots at diametrically opposite points, and so that the yoke may swingon said pivots in a plane coincident with the axis of the revolvingchuck-frame, as indicated in broken lines, Fig. 16. From the under sideof the yoke an arm, 37, projects forward, and carries a cutter, 38. Thiscutter, like the cutter previously described, is best made in circularshape, with its periphery in the form of the cut to be made, and with ashoulder cut in the periphery, as indicated in Fig. 18, to present acutting-point. In this case the edge of the cutter is required only tocut off and trim the mouth of the shell; hence it presents a sharp orinverted V-shaped edge. brought into cutting position or removedtherefrom by a swinging movement imparted to the yoke 36. This swingingmovement is produced by means of a hollow shaft, 39, arranged within thetube 33, and so as to re ceive longitudinal movement therein, butwithout rotation. Longitudinal movement is imparted to the shaft 39 fromthe rockshaft 26 by an arm, 40, 011 the said rock-shaft 26, inlinkconncction with an arm, 41, extending from a transverse rock-shaft,42, as seen in Figs. 2 and 16. From the rock-shaft 42 an arm, 43,extends upward, bifurcated at its upper end to embrace an annulargrooved collar, 44, on the shaft 39, studs 45 in the end of thebifurcated arm entering the annular groove in the said collar, as seenin Fig. 2, so that the rocking movement of the shaft 26 will impart alongitudinal vibratory movement to the arm 43, and a correspondinglongitudinal reciprocating movement to the shalt 39. The shaft 39extends through the yoke into .the chuck-frame, and to that end of theshaft 39 an arm, 46, is applied,which moves longitudinal- 1y with theshaft 39. At its upper end the arm 46 is connected by a link, 47, to theupper edge of the yoke 36; hence as the shaft 39 is moved forward, asindicated in broken lines, Fig. 16, it takes with it the arm 46, andthrough the link-connection 47 carries the upper end of the yoke 36 alsoforward, turning the yoke upon its pivots, and thereby turns the cutterdownward away from its active or cutting position, as indicated inbroken lines, Fig. 16; but on the rear movement of the shaft 39 the arm46 returns and brings the cutter up to its work, as seen in Fig. 16, thecutter trimming the mouth of the shell at the same time the head isbeing trimmed. This cut not only finishes the mouth of the shell, butbrings the shell to the required length; and as theintroduction of theshell is to a positive predetermined position with relation to the chuckand the respective cutters, it follows that allshells so trimmed will beof uniform length. The time at which the cutters are presented to thustrim the shell, as before stated, occurs while the carrier is returningto receive asec- 0nd shell. After the shell has been trimmed, it isremoved from the chuck by means of a longitudinally-movable spindle, 48,which extends entirely through the hollow shaft 39. At its rear end itis in connection with one arm, 49, of a lever hung upon a transverserockshaft, 50, at the extreme end of the ma chine. To this rock-shaft arocking movement is imparted by means of a cam, 51, on the drivingshaft, through a lever, 52, and its connection 53, with an arm, 54,extending down from the rock-shaft 50. (See Figs. 2 and 16.) After theshell has been trimmed,

The cutter is the grasp of the jaws of the chuck is released, as beforedescribed. Then the spindle 48 advances, as indicated in broken lines,

Fig. 16. The head of the spindle comes against the open end of the shelland forces it outward and away from the jaws, and so that it may bedelivered from the machine. This may be directly from the jaws into anysuitable conductor; but I prefer to mechanically transfer the trimmedshell to a position for discharge, as into a tube, which will conduct itto a suitable receptacle prepared for the purpose. To this end Iconstruct the carrier K with a pair of spring-jaws, 56, (see Fig. 12,which extend at right angles to the recess in the carrier which firstreceives the shell, and so that when the carrier is in its position toreceive a shell the jaws 56 stand in a longitudinal plane, and in linewith the shell then in the jaws of the chuck, and as seen in Fig. 4. Theadjacent faces of these jaws are of a shape to readily embrace theshell, as seen in Fig. 9. They are elastic, as indicated in Fig. 12, andfrom the bearing-point the jaws are inclined in both directionslongitudinally, as seen in Fig. 12. At the time the shell has beentrimmed, as before described, the jaws 56 stand in line with the shell,and as it is forced outward by the advance of the spindle 48 it passesbet-ween the jaws 56, as indicated in Figs. 4 and 12, the jaws yieldingfor such re-' ception of the shell, and holding it by a frictionalcontact in that position, and, as seen in Fig. 4, free from the chuck,and so that when next the carrier is turned to present the second shell,57, as seen in Fig. 7, the first shell, 58, is carried down by the jawsinto avertical position, as seen in Fig. 7, and is there held, thecarrier resting while the shell 57 is trans ferred to the chuck, asbefore described. The shell 58, transferred by the jaws 56, as beforedescribed, stands beneath a finger, 59, fixed in avertical slide, 60. Tothe slide 60 an up and down movement is imparted by a cam,61,

on the driving-shaft, through a lever, 62, one

arm, 63, of which is connected to the slide by a link, 64, as seen inbroken lines, Fig. 7,and

enter and pass freely through to its destina-v tion without liability ofinjury to the shell, a conducting device common in cartridge-makin gmachinery. The shell being thus delivered from the carrier and thesecond shell introduced into the chuck, the carrier is returned, asbefore described. The carrier K is turned to presentthe shell from thefeeding'tube to the chuck by the action of the spring T, and istherefore not a positive movement, for the reason that if,perchance,ashell is not entirely passed from the tube into the carrier, the carrierwould be clogged, and a positive movement under such circumstances mustnecessarily break something; or if from any cause the delivery movementof the carrier should be clogged, a like result would follow; hence itis that the delivery movement is made under the action of a springinstead of positive; but it is necessary that the carrier shall stand inone of its two extreme positions before the follower 18 advances, and sothat, should the delivery movement of the carrier be interrupted, it maybe returned to its position to receive the shell from the tube, and alsobring the shell which has been received from the chuck back into linewith the chuck, and so that as the follower next advances it will simplyreturn the shell into the chuck, and thereby avoid jamming the shellagainst the face of the chuck, which would be the case were it out ofline with the chuck and follower. To avoid such a difficulty, I arrangeadog, 65, hung upon apivot, 66,witha spring, 67, beneath it, thetendency of which is to lift the dog. lVhen the dog is raised, as seenin Fig. 4, its nose 68 is outside the path of a flange, 69, Figs. 12 and14, on the side of the carrier, and so that as the carrier is rotated itescapes the nose of the dog. On the back of the dog is a forward andupward incline,

70, and projecting from the slide 19 is a stud, 71, and which, as theslide 19 advances, strikes the incline 70 on the dog, and turns the noseof the dog downward, as seen in broken lines, Fig. 7 butbefore thismovement occurs the carrier has been turned to its position fordelivering the shell. If, however, the carrier should have been cloggedin its movement, as before described, such interruption in the movementof the carrier will occur beforethe flange 69 on the carrier shall haverisen so far as to escape the nose of the dog, as indicated in Fig. 23.Then as the dog descends its nose will strike the flange 69, and willreturn the carrier to its place of rest, bringing it to a bearing upon astop, 72, and thiswill occar before the follower shall have reached thecarrier, so that should the carrier fail to perform its movement in timeto present a shell, it will be returned and held until the followershall have advanced and returned and until the parts are ready for thenext movement, and the dog will so continue until the clogging of thecarrier is removed. In this case the machine will simply go through itsmovements without performing work.

For nicety of work it is necessary that the cutter 31, which trims themouth of the shells, shall only advance to a certain predeterminedpoint. Generally the action ofthe cam will be sufficient for thispurpose; but for greater precision I construct the cutter-holder 23 withan arm, 7 3, and in this arm Iarrange an adj ustable screw, 74, which,when the cutter has arrived at its extreme inward position, will come toa bearing against a stationary adjacent portion of the machine, asindicated in Fig. 22.

It will be apparent that it is necessary that the shells shall bepresented to the carrier with their head downward; but it will sometimesoccur that a shell will enter the feeding-tube mouth downward. Toprovide againstashell in this condition entering the carrier, I hang aloose gravity-dog, 75, upon a pivot, 76, the nose 77 of the dogextending through a slot in the tube so that it will hang within thetube. A shellstriking this dog-head first will cause the dog to swingoutward, as indicated in broken lines, Fig. 4, so that the shell willescape and pass freely to its position in the carrier; but should theshell be presented inverted or mouth downward, then the mouth of theshell will catch upon the hook-shaped nose of the dog, and so engage thedog that it cannot turn outward. In that case the movement of the columnof shells will beinterrupted until such misplaced shell is removed.

I have represented the chuck as having conical jaws, in which thegrasping or radial movement is produced by alongitudinal movement of thejaws, but it will be understood that many of the known chucks may besubstituted for the particular construction which I have illustrated,and it will also be evident to those skilled in the art that many of thedetails of construction may he changed without departing from myinvention, the details which I have shown being the best known to me toproduce the desired result.

I have represented the machine as adapted to perform the two operationsof trimming the head and trimming the mouth; but in cases where the headonlyis required to be trimmed, the mouth-trimming portion may beomitted, or in cases where only the mouth-trimming is required, then thehead-trimming mechanism may be omitted.

I have thus far described the invention as applicable to trimmingcartridge-shells, but the invention is adapted to many other uses, such,for instance, as trimming the mouth of cup-shaped tubes where such workis required, or for various other purposes. Where work is required to beperformed upon one end of a cylindrical article, it may be introducedinto the chuck and the proper tool applied to the tool-holder to bepresented and perform its work upon the inwardly-projecting end of sucharticle. I therefore do not wish to be under stood as limiting myinvention 'to any 'particular use, and-from the foregoing it will beevident that the carrier and presenting device may be omitted, thechuck, the chuck frame, and tool-operating mechanism employed with anysuitable device by which the article may be introduced into the chuckfor the operation of the tool; or such article may be introduced byhand, and the machine in that case consist only of the operativemechanism shown in Fig. 4.
